Abstract:
PROBLEM TO BE SOLVED: To provide a method of manufacturing an SiGe heterojunction bipolar transistor which reduces the SiGe base resistance. SOLUTION: An SiGe heterojunction bipolar transistor comprises a semiconductor substrate with a collector and a subcollector. The collector and the subcollector are formed between isolation regions existing within the substrate. Each isolation region comprises a recessed surface and a nonrecessed surface and these surfaces are formed by a lithography and an etching. An SiGe layer is formed on the substrate and the recessed and nonrecessed surfaces of each isolation region. The SiGe layer comprises a polycrystalline Si region and an SiGe base region. A patterned insulating layer is formed on the SiGe base region and moreover, an emitter is formed on the patterned insulating layer and comes into contact with the SiGe base region through an emitter window aperture.
Abstract:
Ferro-electric capacitor modules, methods of manufacture and design structures. The method of manufacturing the ferro-electric capacitor includes forming a barrier layer on an insulator (18) layer of a CMOS structure (10). The method further includes forming a top plate (32) and a bottom plate (28) over the barrier layer. The method further includes forming a ferro-electric material (30) between the top plate (32) and the bottom plate (28). The method further includes encapsulating the barrier layer, top plate (32), bottom plate (28) and ferro-electric material (30) with an encapsulating material (36). The method further includes forming contacts (20,44a) to the top plate (32) and bottom plate (28), through the encapsulating material (36). At least the contact (44a) to the top plate (32) and a contact (20) to a diffusion of the CMOS structure are in electrical connection through a common wire.
